The primary ethical responsibility of engineers is to protect the public health and safety. This means that engineers must design and build products and systems that are safe for the public to use.

Engineers have a role to play in promoting sustainable development by developing technologies that minimize environmental impact. This includes developing renewable energy sources, energy-efficient technologies, and technologies that reduce pollution.

Engineers have an ethical responsibility to be honest and forthright with their employers about potential risks and problems. This means that engineers must disclose any potential risks or problems that they identify in the course of their work, even if they believe that doing so may harm their employer's interests.

Engineers have an ethical responsibility to protect the public health and safety, to provide the public with accurate and reliable information about engineering projects, and to be responsive to the public's concerns about engineering projects.

Engineers have an ethical responsibility to minimize the environmental impact of their work, to protect the environment from pollution and degradation, and to promote the use of sustainable technologies.

Engineers have an ethical responsibility to design and build structures and systems that will last for many years, to use resources wisely and to avoid waste, and to develop technologies that will benefit future generations.

Engineers have an ethical responsibility to be respectful and cooperative, to share knowledge and expertise, and to mentor and support younger engineers.

Engineers have an ethical responsibility to maintain their professional competence, to act with integrity and honesty, and to avoid conflicts of interest.

Professional engineering societies have a role to play in promoting ethical conduct among engineers by developing and enforcing codes of ethics, providing continuing education and training on ethical issues, and investigating and disciplining engineers who violate ethical codes.

Government has a role to play in regulating the ethical conduct of engineers by licensing engineers and setting standards for engineering practice, investigating and prosecuting engineers who violate ethical codes, and providing funding for engineering research and education.

The public has a role to play in promoting ethical conduct among engineers by holding engineers accountable for their actions, reporting engineers who violate ethical codes, and supporting engineers who act ethically.

Engineers face a number of challenges in fulfilling their ethical responsibilities, including conflicting ethical obligations, pressure from employers or clients to compromise ethical standards, and lack of knowledge or experience in dealing with ethical issues.

Engineers can overcome the challenges they face in fulfilling their ethical responsibilities by seeking out mentors and advisors who can provide guidance on ethical issues, educating themselves about ethical issues and the ethical codes that apply to their profession, and developing a personal code of ethics to guide their decision-making.
